Pearland police are now looking into a new and disturbing lead in the case of a Pearland man facing four counts of sexually assaulting a child.

Tad Jeremy Costin, 42, was arrested Nov. 1 after a Liberty County investigation into child pornography led authorities to him. His girlfriend, Julia Lack, 26, was arrested one week later and charged with one count of possession of child pornography.

Pearland police now say that Costin had an ex-girlfriend that may have operated an in-home overnight babysitting service in Clear Lake, where he could have had access to children, according to Pearland police spokesman Lt. Onesime Lopez.

The former girlfriend is not a suspect in the case, Lt. Lopez added.

“These are victims from the local area,” Lt. Lopez told the Pearland Journal on Tuesday. “We are asking parents with children who may have came into contact the with suspect to come forward if they have any information.”

Though he only faces four counts of aggravated sexual assault of a child at this time, prosecutors have said many more victims could be discovered. Police believe that Costin could have been making child porn videos since at least 1999.

Officials are now going about the grim task of identifying some of the victims on a computer memory card that contains hundreds of images of Costin engaged in sexual acts with young children, some of whom officials believe ranged in age from 4 to 7 years.

Costin is being held in Harris County jail on $4 million bond.

Since his arrest, officials have urged anyone with knowledge of potential additional victims to come forward. Anyone with information should contact Houston Crime Stoppers at 713-222-TIPS (8477).
